How to Execute the Invention First Mode

[0091] The indoor unit and the air conditioning according to the First Modality of the present invention are described below with reference to the attached drawings.

Basic Indoor Unit Configuration

[0092] Figure 1 is an external perspective view of an internal unit 1 according to a First Modality of the present invention. Figure 2 is a schematic cross-sectional plan view of the indoor unit 1. Figure 3 is a cross-sectional view taken on the AOA line of figure 2. Figure 4 is a plan view of a decorative panel of the indoor unit 1 seen from from an air-conditioned environment. Figure 5 is an enlarged view of Figure 3, showing a channel portion corresponding to a main outlet 32d. Figure 6 is a cross-sectional view taken on line B-B of figure 4.

[0093] As shown in figure 1, the indoor unit 1 is an indoor unit built into the ceiling, and includes a compartment 2 housing several component units within it. The compartment 2 is configured in a main body 2a of the compartment, and a decorative panel 3 disposed under the main body 2a of the compartment. The main body 2a of the compartment, as illustrated in figure 3, is disposed inserted in the opening formed in the U ceiling of an air-conditioned environment. The decorative panel 3 is fitted into the ceiling opening U. The indoor unit 1 can be controlled by operating a connected remote control 83 connected via a W cable placed along the surface of the ceiling (not shown).

Compartment Main Body Configuration

[0094] As illustrated in figures 2 and 3, the main body 2a of the compartment has a box-like shape with a virtually octagonal open bottom with longer sides and shorter sides that alternate as seen in a plan view, and includes an octagonal top frame 21 formed by continuous and alternating longer sides and shorter sides, and side frames 22 extending downwardly from side frames 22a to 22d corresponding to the longer sides of top frame 21, and side frames 22e a 22h corresponding to the shorter sides of the upper frame 21. For example, as shown in figure 2, side frame 22a and side frame 22b are arranged virtually orthogonal to each other, via side frame 22e. The side frames 22b and 22c, the side frames 22c and 22d, and the side frames 22d and 22a, are also arranged in a virtually orthogonal manner.

[0095] The side frame 22e is arranged at an angle of approximately 135 degrees with respect to the adjacent side frames 22a and 22b. Side frames 22g and 22h are also arranged at an angle of approximately 135 degrees with respect to adjacent side frames, as with side frame 22e. It is observed that the side frame 22f has a different shape from the other side frames, because the side frame 22f, is through which a refrigerant pipe is provided to exchange a refrigerant between a heat exchanger 6 and an indoor unit (not shown) ). The side frames 22e to 22h are each provided with a fixing clamp 23 used to install the main body 2a of compartment in the ceiling space. In the main compartment body 2a, the lengths of the longest and shortest sides of the upper frame 21 are determined so that the shape including the fixing clamps 23 appears virtually rectangular as seen in a plan view.

Decorative Panel Configuration

[0096] As illustrated in figures 1 and 4, the decorative panel 3 is a virtually rectangular plate unit when viewed in a flat view, and configured to form mainly a main panel body 3 fixed to the lower portions of the main body 2a of the compartment. The main body 3a of the compartment has four side portions of panel 30a to 30d (side portions) formed alternately and continuously and four corner portions of panel 30e at 30h. The side portions of panel 30a to 30d correspond to the side frames 22a to 22d, respectively, of the main body 2a of the compartment. The corner portions of panel 30e to 30h correspond to side frames 22e to 22h, respectively, of the main body 2a of the compartment.

[0097] As illustrated in figure 1, the main body 3a of the panel includes an inlet 31 formed virtually at its center to draw air from the air-conditioned environment, and four main outlets 32a to 32d, respectively corresponding to the side portions of panel 30a to 30d, through which the air that is inside the main body 2a of the compartment is released to the environment with air conditioning. In the present embodiment, the entrance 31 is a virtually square opening. The four main outlets 32a to 32d have virtually the same shape, and are arranged along the side portions of panel 30a to 30d, respectively.

[0098] Furthermore, as illustrated in figures 1 and 4, the main panel body 3a includes auxiliary outputs 32 and 32h, corresponding in position to the corner portions of panel 30e and 30h, respectively. In addition, as illustrated in Figure 1, a four-sided, flat annular, lower panel portion 3b is provided around the entrance 31 on the lower surface of the main panel body 3a being surrounded by the four main outlets 32a to 32d . As shown in Figure 4, the bottom panel portion 3b has edge portions 50a to 50d in the vicinity of the main outlets 32a to 32d, on the inlet side 31 of the main outlets 32a to 32d.

[0099] As illustrated in figure 4, the entrance 31 is arranged on the internal side of the main exits 32a to 32d. Inlet 31 includes an inlet grid 33, and a filter 34 provided to remove dust in the air drawn through inlet 31. In addition, as illustrated in figure 4, the main outlets 32a to 32d are provided with fins 35a to 35d, respectively that can be oscillated around a geometric axis along the longitudinal direction. The fins 35a to 35d are components of long, narrow, virtually rectangular blades that have virtually the same shape extending along the longitudinal direction of their respective main outlets 32a to 32d. The fins 35a to 35d can be oscillated around a geometric axis along the longitudinal direction of the main outlets 32a to 32d as they are rotatably supported on the decorative panel 3.

Configuration of marked sections

[00100] As illustrated in figure 4, the sections marked 60a to 60d for individually recognizing the main outlets 32a to 32d or the fins 35a to 35d are formed in the edge portions 50a to 50d of the lower surface portion 3b of the panel. The sections marked 60a to 60d are formed as "□" □ □ and "□ □ □ figures The sections marked 60a to 60d are formed on the input side 31 of the main exits 32a to 32d. The figures a" □ □ □ □ "correspond to to the numbers "1" to "4", respectively, which, in figure 4, are arranged in ascending order in a counterclockwise direction. Figures a "□ □ □ □" are arranged in positions that correspond to the main exits 32a to 32d, respectively. As illustrated in figure 6, the sections marked 60a to 60d are provided as indented sections in the edge portions 50a to 50d. Note that the areas surrounding the sections marked 60a to 60d have a matte finish ( surface texture), while the marked sections are brighter (bright portions) with respect to the environment.

[00101] The fins 35a to 35d can be programmed to the oscillation state that involves a continuous activation by the motors 40a to 40d of the fins (see figure 7), or to the stopped state in which the direction of air release coming from the air conditioning is fixed. In the adjustment for the oscillating state, the fins 35a to 35d oscillate continuously to change the direction of air release coming from the air conditioner. On the other hand, in the adjustment for the fixed state, the fins 35a to 35d assume the predetermined direction of the wind and fix the direction of release of the air that comes from the air conditioner in a certain direction. As illustrated in figure 4, the fins 35a to 35d can oscillate to individually change the wind directions into the air-conditioned environment through the main outlets 32a to 32d.

[00102] For example, as illustrated in figure 5, the wind direction of the air flow X released to the air-conditioned environment through the main outlet 32d can be varied by the flap 35d up and down with respect to the bottom surface ceiling U. As illustrated in figure 5, the wind direction of the airflow X can have six adjustments: "wind direction 1" to "wind direction 5", and "oscillation" in which the fins oscillate across the strip " wind direction 1 "to" wind direction 5 ". The wind directions are such that the wind is tilted further down in the ascending order of the numbers "wind direction 1" to "wind direction 5". It is observed that the wind directions of the air flow X released to the air-conditioned environment through the other main outlets 32a to 32c are also variable in the upward and downward direction with respect to the lower surface of the U ceiling, and can have any one of six adjustments, although not described.

[00103] As illustrated in figure 3, inside the main body 2a of the compartment, mainly a fan 4 is provided that ventilates air to the periphery after pulling air into the air-conditioned environment inside the main body 2a of the compartment through the entrance 31 of the decorative panel 3, and a heat exchanger 6 arranged around the periphery of the fan 4. In the present embodiment, the fan 4 is a turbo fan, and includes a fan motor 41 located in the center of the upper frame 21 of the body 2a main compartment, and an impeller 42 attached to the fan motor 41 and rotated by it.

[00104] Impeller 42 includes a disk-shaped end plate 43 attached to the fan motor 41, a plurality of blades 44 provided at the periphery on the bottom surface of end plate 43, and a disk-shaped end ring 45 provided on the underside of blades 44 and having an opening in the center. By rotating the blades 44, the fan 4 can draw air into the impeller 42 through the opening of the end ring 45, and can release the air admitted to the impeller 42 towards the periphery of the impeller 42.

[00105] In the present embodiment, the heat exchanger 6 is a keel-shaped cross-tube heat exchanger panel formed by being folded around the periphery of the fan 4, and is connected via a refrigerant pipe to an external unit (not shown) installed, for example, outside. The heat exchanger 6 is adapted to serve as an evaporator for the refrigerant that is passing in the cooling mode, and a condenser for the refrigerant that is passing in the heating mode. In this way, the heat exchanger 6 can cool the air in the cooling mode and heat the air in the heating mode by exchanging heat from the air drawn into the main body 2a of the compartment through the inlet 31 by the fan 4.

[00106] A drain vessel 7 for receiving drained water generated by the condensation of air moisture in the heat exchanger 6 is disposed on the underside of the heat exchanger 6. The drain vessel 7 is attached to the lower portion of the main body 2a compartment. As illustrated in figures 2 and 3, the drain container 7 includes four main discharge holes 72a to 72d that communicate with the main outlets 32a to 32d of the decorative panel in communication with the main outlets 32a to 32d of the decorative panel 3, and a drained water receiver groove 73 formed on the underside of the heat exchanger 6 to receive the drained water. The main discharge holes 72a to 72d are shorter along the longitudinal direction of their respective main outlets 32a to 32d. The length of the main discharge port 72c is particularly shorter along the longitudinal direction than the lengths of the other main discharge ports 72a, 72b and 72d, because the main discharge port 72c is placed between a drain pump 8 arranged in the side of the side frame 22g and is used to drain the drained water accumulated in the groove of the drain water container 73, and the portion crossed by the pipe with refrigerant running in the side frame 22h.

Control Unit Configuration

[00107] As illustrated in figure 7, the indoor unit 1 includes a control unit 80 that controls parameters such as the speed of rotation of the fan 4, and the wind directions of the fins 35a to 35d. The control unit 60 mainly includes a microcomputer equipped with a CPU 81 and memory 82. The control unit 80 receives control signals by the connected remote control 83, and, when receiving the signals, CPU 81 executes the control program stored in the memory 82 to drive the fan motor 41 of the fan 4, and the motors 40a to 40d of the vane that drive the fins 35a to 35d. In this way, the control of the speed of rotation of the fan 4 and the wind directions in the fins 35a to 35d is enabled.

Connected Remote Control Configuration

[00108] Figure 8 is a front view of the remote control connected 83 according to the present mode. Figure 9 is a schematic diagram of control blocks of the connected remote control 83. Figure 10 is a diagram representing several screens displayed in a display section 85 of the connected remote control 83.

[00109] As illustrated in figure 8, the connected remote control 83 includes a remote control compartment 84, the display section 85, several operating buttons 86 to 91, memory 92 storing various data relating to the operation of the internal unit 1, a CPU 93, and database 94. Remote control compartment 84 is virtually rectangular in shape, and houses CPU 93 and other components. Display section 85 is capable of displaying several formatting screens, in addition to a basic screen of several screens containing menus.

[00110] Operational buttons 86 to 91 (operating sections) are provided on the front face of remote control compartment 84. The operate / stop button 86 is a button that a user uses to enter an instruction to start or stop the operation of the unit internal. The menu / setting button 87 is a circular button surrounded by a selector button in the shape of a thread 88, and is used by a user when changing the various settings of the indoor unit 1. Pressing the menu / setting button 87 allows the display section 85 display a D1 main menu screen. The menu / adjustment button 87 also works to adjust each configuration item selected on the main menu screen D1.

[00111] The selector button 88 has an up selector 88u, a down selector 88d, a selector on the left 88I, and a selector on the right 88r, each marked with the Δ symbol indicating the direction (ascending, descending, for the left or right). The four selectors 88u to 88r are integrated in appearance, and represent the regions allocated above, below, left and right of the 88 selector button. Pressing the 88u selector to 88r moves the cursor, allowing a user to choose, for example, a configuration item or a configuration value for indoor unit 1.

[00112] The mode switch button 89 is a button used to switch the operating mode of the indoor unit between heating mode and cooling mode. The wind volume / wind direction button 90 is a button that a user uses to change the total wind volume / total air direction of outlets 32a to 32d. CPU 93 executes a program to control the operation of indoor unit 1. Database 94 stores various types of information, including basic layout data to form the basic screen D0 shown in figure 10, layout data from the main menu to form the main menu screen D1 shown in figure 11, and detailed configuration layout data for the setting screen D2 of the total wind volume / total wind direction shown in figures 12 and 13, the D3 screen for individual wind direction configuration shown in figure 14, and screen D4 for checking wind direction settings shown in figure 15.

Screen Settings Shown in Display Section 85

[00113] Figures 10 to 15 represent several screens shown in the display section 85 of the connected remote control 83.

Basic Screen Configuration

[00114] Figures 10 (a) and 10 (b) represent examples of the basic screen D0 shown in the display section 85. As shown in figure 10, the basic screen D0 is divided between a display region 100 that indicates the configuration of current temperature, a display region 102 that indicates the current wind volume state configuration, and a display region 103 that indicates whether the wind directions are determined separately for the main outlets 32a to 32d.

[00115] As shown in figure 10 (a), the display region 100 shows the character "26 ° C" as the current temperature setting, the display region 101 the character "Cooling" as the current operating mode setting , and the display region 102 the character "Fast" as the current wind volume setting. In figure 10 (b), the display region 100 displays the character "26 ° C" as the current temperature setting, the display region 101 the character "Cooling" as the current operating mode setting, and the display 102 the character "Auto" as the current wind volume setting.

[00116] Display region 103 displays the character "Individual Configuration" when the wind direction is determined separately for at least one of the main outlets 32a to 32d, and does not show any text when the wind direction is not determined individually for any of the main fins 32a to 32d. In figure 10 (a) and 10 (b), the wind direction is determined separately for any of the outputs 32a to 32d, and thus the display region 103 shows the character "Individual configuration". The display region 103 can show the character "No Individual Configuration" when the direction is not separately determined for any of the outputs 32a to 32d. Pressing the menu / setting button 87 on the basic screen D0 changes the display to the main menu screen D1 shown in figure 11. Pressing the 90 wind volume / wind direction button on the basic screen performs the interrupt processing and changes the display for the D2 total wind volume adjustment screen D2 shown in figure 12.

Main Menu Screen Configuration

[00117] Figure 11 (a) and (b) represents examples of the D1 screen of the main menu shown in the display section 85. As shown in figure 11, the D1 screen of the main menu has six adjustment setting items for the unit internal 1. Specifically, menu captions are listed that correspond to "Service Contact Information / model name", "Individual wind direction setting", "Check wind direction setting", "Timer setting" , "Power save setting", and "Useful functions".

[00118] Figure 11 (a) represents the initial screen that appears when switching to the D1 screen of the main menu. On the home screen, the cursor is on the main legend that corresponds to the configuration item "Contact information for service / model name" from the different configuration items. Pressing the down selector 88d in this state moves the cursor down in the display section 85 in turn, allowing the user to select a configuration item by placing the cursor on one of the "Individual wind direction configuration" menu captions in "Useful functions".

[00119] For example, as shown in figure 11 (b), press the menu / adjustment button 87 while selecting the item "Individual wind direction configuration", the main D1 screen of the menu changes to the D3 individual configuration screen direction as shown in figure 14. The user can then determine the wind direction separately for any of the main outlets 32a to 32d, based on the D3 screen for individually configuring the wind direction. In addition, for example, pressing the menu / setting button 87 when the "Check wind direction setting" configuration item is selected, the main menu screen D1 changes to the wind direction settings check screen D4 shown in figure 15. In the D4 screen for checking the wind direction settings, the user can then visually confirm all the wind directions configured at that time for the main exits 32a to 32d.

Setting the Total Wind Volume Adjustment Screen / Total Wind Direction

[00120] Figures 12 (a) to (e) and figure 13 (a) to (h) represent examples of the D2 screen for adjusting the total wind volume / total wind direction displayed in the display section. 85. As shown in figures 12 and 13, the D2 screen for adjusting the total wind volume / total wind direction is divided into display regions 104 and 105. The captions in the menu that correspond to the two setting items "Adjust the volume total wind "and" Adjust total wind direction "are displayed at the top of each region of the display.

Total Wind Volume Adjustment Operation

[00121] Figure 12 (a) represents the initial D2-0 screen of the D2 screen for adjusting the total wind volume / total wind direction. On the home screen, the cursor is on the menu legend that corresponds to the configuration item "Adjust total wind volume". The display region 104 on the home screen shows the character "Fast", indicating that the total wind volume at that time is "Fast" for all main exits of main exits 32a to 32d. The total wind volume of the main outlets 32a to 32d can be set to "Strong" (figure 12 (b)), "Weak" (figure 12 (c)), or "Auto" (figure 129d)).

[00122] Pressing the cancel button 91 on the initial screen D2-0 shown in figure 12 (a), changes the display to the basic screen D0 in figure 10. On the other hand, pressing the down selector 88d on the initial screen D2-0 changes the display to the D2-1 settings screen (figure 12 (b)), the D2-2 settings screen (figure 12 (c)), and the D2-3 settings screen (figure 12 (d)) by your turn. Pressing the 87 menu / setting button in each display state changes the display in the display region 104 from "Strong" to "Weak", and to "Auto", allowing the user to determine the total wind volume for the main outlets 32a to 32d at once. The display returns to the previous screen by pressing the 88u up selector.

Total Wind Direction Adjustment Operation

[00123] Pressing the selector on the right 88r in the state shown in figure 12 (a) moves the cursor to the menu legend corresponding to the configuration item "Adjust total wind direction", and the initial screen D2-0 shown in figure 12 (a) changes to the initial screen D2-4 for an adjustment of the total wind direction shown in figure 13 (a). Note that, in this example, the text "Individual wind direction setting" displayed at the bottom of display region 105 on the home screen means that the wind direction was determined separately for "Wind direction 1" for the output main 32c, and the direction to the remaining main exits 32a, 32b, and 32d, other than main exit 32c is determined immediately, as follows. As an example, main outputs 32a, 32b and 32d, different from main output 32c can be selected by setting "Wind direction 1" for main output 32c in advance, and the total wind direction can be determined immediately only for positions wind direction of fins 35 a, 35b, and 35d, of main fins 32 a, 32b, and 32d selected in this way. The text "Wind direction 1" displayed in the center of the display region 105 means that the total wind direction of the main outlets 32a, 32b, and 32d can be adjusted to any of the "Wind direction 2" (figure 13 (b )), "Wind Direction 3" (figure 13 (c)), "Wind Direction 4" (figure 13 (d)), "Wind Direction 5" (figure 13 (e)), and "Oscillation" ( figure 13 (f)).

[00124] Pressing the down selector 88d on the initial screen shown in figure 13 (a), changes the display to the settings screen D2-5 (figure 13 (b)), the settings screen D2-6 (figure 13 (c )), the settings screen D2-7 (figure 13 (d)), the settings screen D2-8 (figure 13 (e)), and the settings screen D2-9 (figure 13 (f), in turn once,

[00125] On the screens shown in figures 12 and 13, the character "Individual wind direction configuration" is shown to indicate that the wind direction is individually configured for any of the main outputs. However, the display can indicate which of the main outlets have an individual wind direction setting. Specifically, in the example described here, the display may indicate that the wind direction has been individually configured for main output 32c. In addition, on the screens illustrated in figures 12 and 13, the display can indicate which output is subject to the "Total wind direction setting". Specifically, in this example, the display may indicate that the main outlets 32a, 32b and 32d are those subject to the "Total wind direction setting".

Configuring the Individual Wind Direction Configuration Screen

[00126] Figures 14 (a) to 14 (g) represent examples of the individual wind direction setting screen D3 shown in display section 85. As shown in figure 14, the individual wind direction setting screen D3 is divided into display regions 106 and 107. Display region 106 schematically shows indoor unit 1 as seen from the environment, and symbols "□" to "□ □ □ □" representing the marked sections 60a to 60d of the edge sections 50a to 50d are shown in the diagram. Display region 107 shows the state of the current wind direction determined at that time for main outputs 32a to 32d.

[00127] Figure 14 (a) represents the initial screen D3-0 with regard to the individual wind direction configuration. In the initial screen D3-0, the schematic view displayed in the display region 106 includes an inverted display, indicating that the main output 32a corresponding to the symbol has been selected. Still on the initial screen D3-0, the number “1” displayed in the central part of the display region 106 corresponds to the main output 32a, and indicates that the main output 32a has been selected. The inverted display and the number thus provide visual information for a user to confirm that output 32a is available for Individual Wind Direction Configuration. Also as shown in figure 14 (a), the character “wind direction 2” is shown in the center of the display region 107 on the initial screen D3-0, indicating that main output 32a has been set to “wind direction 2” . Operation for Individual Wind Direction Configuration

[00128] The wind direction of the main outlet 32a can be selected from "wind direction 1" to "wind direction 5" and "Oscillation" when operating the upward selector 88u or the downward selector 88d in the state shown in figure 14 ( THE). Pressing the menu / adjustment button 87 while either direction is selected determines the main output 32a to the selected wind direction. On the other hand, Pressing the cancel button in the state shown in figure 14 (A), changes the initial screen D3-0 to the main menu screen D1 shown in figure 1. Press the right selector 88r in the state shown in figure 14 ( a), changes the initial screen D3-0 to the settings screen D3-1 (figure 14 (b)), the settings screen D3-2 (figure 14 (c)), and the settings screen D3-3 ( figure 14 (d)) in turn, allowing the user to determine any of the "wind direction 1" to "wind direction 5" and "Oscillation" for main outputs 32b to 32d.

Operation for Individual Wind Direction Configuration for Main Output 32d

[00129] As an example, the following describes how the "wind direction 2" determined for main output 32d as in figure 14 (D) is changed to "wind direction 3". Press the down selector 88d on the settings screen D3-3 in figure 14 the display changes to the settings screen D3-4 shown in figure 14 (e), and the display in the central part of the display region changes to the "direction of the wind 3 ". Pressing the menu / setting button 87 while "wind direction 3" is shown allows the wind direction of main outlet 32d to be individually determined for "wind direction 3".

Screen for checking wind direction settings

[00130] Figures 15 (a) and (b) represent examples of the screen for checking the wind direction settings D4 shown in the display section 85. As shown in figure 15, the screen for checking the wind direction settings D4 lists menu captions corresponding to three items for verification: "Output", "Wind Direction", and "Individual Adjustment", from left to right. As shown in (a) and (b) in figure 15, the column under the "Output" check item shows symbols "1 ■" to "4 ■ ■ ■ ■" to individually identify outputs 32a to 32d. The symbols "1 ■" to "4 ■ ■ ■ ■" correspond to the symbols "□" to "□ □ □ □" (see figure 3) to individually identify the main outputs 32a to 32d. Also, as shown in FIG 15 (a) and (b), the column under the "Wind direction" check item shows the wind directions of the main exits 32a to 32d, simultaneously with the symbols "" 1 ■ "a "4 ■ ■ ■ ■". Also, as shown in figure 15 (a) and (b), the column under the "Individual configuration" check item indicates whether the wind direction was determined individually for the main outlets 32a to 32d , and "o" is shown in the cells corresponding to the individually configured main outputs.

[00131] Specifically in figure 15 (a), the main outlets 32a, 32b, and 32d have the configuration of the total wind direction "wind direction

Wind Direction / Wind Volume Adjustment Operation

[00132] The operation of adjusting the wind direction / wind volume of the present mode is described below with reference to figures 16 and 17.

[00133] Figure 16 is a flowchart representing the operation of adjusting the wind direction / wind volume of the present modality. It should be noted that the "wind direction / wind volume adjustment operation" in the flowchart includes "total wind volume adjustment operation", "total wind direction adjustment operation", "individual wind configuration operation" wind direction "and" wind direction setting check operation ", as will be described later.

[00134] First, in step S100 in figure 6, the display section 85 shows the basic DO screen (see figure 10 (a)).

[00135] Then, it is determined in step S102 if the wind direction / volume 90 direction button was pressed. If it is determined that the wind direction / volume 90 direction button has been pressed, the sequence goes to step S104. On the other hand, the sequence goes to step S100 if it is determined that the wind direction / volume 90 direction button has not been pressed.

[00136] In the next step S104, the display section 85 shows the screen for adjusting the total wind volume / total wind volume D2 (see figure 12 (A) to (d) for the group configuration of the total wind volume) for main exits 32a to 32d.

[00137] In the next step S106, it is determined whether a request to change the current wind direction for the main exits 32a, 32b and 32d for another volume has been introduced. If a request to change the wind volume has been entered, the sequence goes to step 108, and the operation to adjust the total wind volume is performed. On the other hand, the sequence goes to step S110 if a request to change the wind volume has not been entered.

[00138] In step S110, it is determined whether a request to change the wind direction established for the main exits 32a, 32b and 32d to another direction was introduced. If a request to change the wind direction has been entered, the sequence goes to step 112, and the operation to adjust the total wind direction is performed. On the other hand, the sequence goes to step 114 if a request to change the wind direction has not been entered.

[00139] In step S114, the display section 85 displays a basic screen D0.

[00140] In the next step S116, the display section 85 displays the Main Menu Screen D1.

[00141] In the next step S118 it is determined whether a request to confirm the wind direction adjustments of the main outlets 32a to 32d was introduced. If a request to confirm the wind direction adjustments for the main exits 32a to 32d was introduced, the sequence goes to step S120. On the other hand, the sequence goes to step S122 if a request to confirm the wind direction adjustments for main outlets 32a to 32d has not been entered.

[00142] In step S120, it is determined whether a request to individually adjust the wind direction of any of the main outlets 32a to 32d has been entered. If a request to individually adjust the wind direction of any of the main outlets 32a to 32d was introduced, the sequence goes to step S126 in figure 17. On the other hand, the sequence goes to step S100 if a request to individually adjust the wind direction of any of the main outlets 32a to 32d has not been entered.

[00143] In step S122, display section 85 displays the screen for checking wind direction settings D4, and the sequence goes to step S100.

Individual Wind Direction Configuration Operation

[00144] Figure 17 is a flow chart representing the individual wind direction configuration operation in the present mode.

[00145] After step S126 in figure 17, display section 85 in step S200 displays the initial screen D3-0 for individual configuration of wind direction (see figure 14 (a)). In the next step S202a, it is determined whether main output 32a has been selected. If main output 32a has been selected, the sequence goes to step S204a, and fin 35a is adjusted to the individual wind direction setting. In step S206a, display section 85 displays the D4 wind direction settings check screen. If main output 32a has not been selected, the sequence goes to step S202b. If main output 32b has been selected, the wind direction of fin 35b is adjusted in step S204b, and the screen for checking wind direction settings D4 is displayed in step S206b. The same process is performed for main outputs 32c and 32d in steps S202c to S206c and in steps S202d to S206d, respectively.

[00146] In the previous wind direction / wind volume adjustment operation, the individual wind direction configuration operation is performed in step S126 of figure 17 after the total wind volume adjustment operation (step S108) and full wind direction adjustment operation (step S112) in FIG 16. However, for example, the total wind volume adjustment operations (step S108) or total wind direction adjustment (step S112) can be performed when interrupting the individual wind direction setting operation at the moment when the wind direction / wind volume button 90 is pressed while executing the individual wind direction setting operation in step 126 of figure 7.

Features of the First Mode air conditioning

[00147] In the air conditioning of the first modality, the fins 35a to 35d, requiring, for example, a change of wind direction can be easily identified just by looking at the sections marked 60a to 60d.

[00148] Furthermore, a user can easily identify the marked sections 60a to 60d, because the marked sections 60a to 60d are three dimensional provided as indented portions at the edges of the portions 50a to 50b in the lower surface portion of panel 3b. Because the marked sections 60a to 60d are formed on the flat surface of the lower surface portion of panel 3b, the marked sections 60a to 60d can be easily recognized from any direction in the environment. Specifically, the recognition of marked sections 60a to 60d from a certain direction in an environment can be difficult when marked sections 60a to 60d are formed on the outside of exits and when areas with marked sections 60a to 60d are slanted in relation to the ceiling surface. It can also be difficult to recognize the marked sections 60a to 60d depending on the direction in an environment when the angle of the fin is changed to fins 35a to 35d having the marked sections 60a to 60d formed directly on them.

[00149] Also, a user can individually identify the main exits 32a to 32d and the fins 35a to 35d with more confidence, because the sections marked 60a to 60d are provided as figures a "□ □ □

[00150] Furthermore, a user can individually identify the main exits 32a to 32d and the fins 35a to 35d with greater confidence, because the sections marked 60a to 60d correspond to the main exits 32a to 32d and the fins 35a to 35d are formed by the layout counterclockwise from the figures to "□ □ □ □" representing the sections marked 60a to 60d.

[00151] Also, a user can individually identify the main exits 32a to 32d and the fins 35a to 35d with even greater confidence, because the vicinity of the marked sections 60a to 60d has a matte finish to make the marked sections 60a to 60d more noticeable in appearance over the environment.

[00152] Also, because the decorative panel 3 and the marked sections 60a to 60d are integrally formed, it is not necessary to go through the laborious procedure of preparing four fins in different ways, which would be otherwise necessary when a marked indented section is provided for each fin. This reduces the number of production steps and the production cost of the air conditioner 1.

[00153] Also, the air from the air conditioner can be sent to the environment more efficiently, because the main outlets 32a to 32d are arranged on the side portions of the panel 30a to 30d, the outermost portions of the product.

[00154] Also, because the inlet 31 is arranged on the inside of the main outlets 31a to 32d, the released air flow can be prevented from being immediately drawn into the inlet.

[00155] Furthermore, because the marked sections 60a to 60d are formed on the inlet side 31 of the main exits 32a to 32d, the marked sections 60a to 60d can be easily checked even when the fins 35a are moving during operation.

[00156] In addition, a user can easily identify fins 35a to 35d by looking at the sections marked 60a to 60d, even when fins 35a to 35d have substantially the same shapes and create difficulty for the user to individually identify fins 35a to 35d.

[00157] Furthermore, the utilization can be improved, because a user looking at the display section 85 of the wired remote control 83 can simultaneously control the main outlets 32a to 32d and the ventilation directions determined at the moment for the ventilation outlets in the verification settings screen D4.

[00158] In addition, a user can easily control the ventilation directions of all main outlets 32a to 32d by looking only at the display section 85, because the ventilation directions of all main exits 32a to 32d are shown in a list of ventilation direction.

[00159] Also, a user can change the ventilation direction positions of the fins 35a to 35d with a remote control based on their memory of the marked sections corresponding to the outlets or fins, even when the remote control 83 is away from the indoor unit 1 .

Second Mode

[00160] The indoor unit according to the Second Mode of the present invention is described below with reference to the accompanying drawings.

Basic Indoor Unit Configuration

[00161] Figure 8 is an external perspective view of the intera unit 101 according to the Second Modality of the present invention. Fig. 19 is a plan view of an intake grille 108 of indoor unit 101 as seen from the air-conditioned environment.

[00162] As shown in figure 18, the indoor unit 101 is an indoor unit hanging from the ceiling including a box-shaped liner 103 provided with main outlets 102a through 102d provided as horizontal openings on the four sides of the liner 103. The indoor unit is arranged on the ceiling surface (not shown). A heat exchanger and a turbocharger fan are housed within the liner 103. Fins 106a to 106d to determine the direction of the air conditioning air ventilation to the environment are provided in rotation to the main outlets 102a to 102d.

[00163] As illustrated in figure 18, the inlet grid 108 having an inlet 107 in the center is attached to the bottom surface of the liner 103 in order to allow the inlet grid 108 to open and close. As illustrated in figure 9, the input grid 108 has side portions 150a to 150d in the vicinity of the main exits 102a to 102d, respectively. As illustrated in figures 18 and 19, the main outlets 102a to 102d are formed along the side portions 150a to 150d, respectively. Inlet 107 is arranged on the inside of main outlets 102a to 102d.

Configuration of the marked sections.

[00164] As shown in figure 19, the sections marked 160a to 160d for individually recognizing the main exits 102a to 102d or the fins 106a to 106d are formed by placing adhesives, numbered "1" to "4", at side portions 150a to 150d. The numbers "1" to "4" correspond to the main exits 102a to 102d, respectively, and are arranged in an ascending order in the counterclockwise direction in figure19. As illustrated in figures 18 and 19, the sections marked 160a to 160d are formed on the inlet side 107 of the main exits 102a to 102d.

Second Air Conditioner Features

[00165] In the air conditioning of the Second Mode, the same effects obtained by the air conditioning of the First Mode can be obtained, because the fins that need, for example, a change of the ventilation direction can be identified individually from the fins 106a to 106d to the look only at the marked sections 160a to 160d formed on the side portions 150a to 150d in the vicinity of the main exits 102a to 102d.

[00166] Also, the sections marked 160a to 160d can be easily formed by placing stickers numbered "1" to "4", to the side portions 150a to 150d.

Third Mode

[00167] The indoor unit according to the Third Modality of the present invention is described below with reference to the accompanying drawings.

Basic Indoor Unit Configuration

[00168] Figure 20 is an external perspective view of the internal unit 201 according to the Third Modality of the present invention. Fig. 21 is a decorative panel 222 of indoor unit 201 as viewed from the air-conditioned environment. Figure 22 is a cross-sectional view taken on line C-C of figure 21.

[00169] The indoor unit 201 is an indoor unit built into the ceiling, and includes a cover 202 (figure 20) in which components such as a ventilation unit, a heat exchanger, and a box of electrical components are contained. The cladding 202 has the shape of a horizontally rectangle with a decorative panel 222 attached to the cladding of the main body 221. As illustrated in figure 20, the decorative panel 222 is provided detachable from the cladding of the main body 221, covering the lower surface of the main body 221. Horizontally long inlets 223 are provided through decorative panel 222 in the center, and horizontally long main outlets 224a and 224b are provided along side portions 227a and 227b on both sides. Fins 226a and 226b to determine the direction of air conditioning air ventilation to the environment are provided in rotation for main outlets 224a to 224b. As shown in figure 20, an input grid 225 is detachably attached to inputs 223. Inputs 223 are arranged on the inside of main outputs 224a to 224b.

Configuration of marked sections

[00170] As illustrated in figure 21, the sections marked 260a and 260b for individually recognizing the main exits 224a to 224b and the fins 226a and 226b are formed on the outer side of the decorative panel 22, in the vicinity of the main exits 224a and 224b. The sections marked 260a and 260b are formed as the figures and "□ The figures and" □ □ "correspond to main exits 224a and 224b, respectively. The sections marked 260a and 260b are formed on the opposite side of entries 223 in relation to the main exits. 224a and 224b As shown in figure 22, marked sections 260a and 260b are provided three-dimensionally as raised portions in decorative panel 222.

Characteristics of Third Mode Air Conditioning

[00171] In the air conditioning of the Third Mode, the same effects obtained for the air conditioning of the First Mode can be obtained, because the fins that need, for example, a change of the ventilation direction can be identified individually of the fins 226a and 226b when looking only at the marked sections 260a and 260b formed in the vicinity of main exits 224a and 224b.

[00172] While certain embodiments of the present invention have been described with reference to the accompanying drawings, it should be understood that specific configurations are not limited to the embodiments described above. In addition, the scope of the present invention is defined not only by the descriptions of the preceding embodiments, but by the embodiments, including all modifications within the scope and meaning of the equivalents of the embodiments.

Variations

[00173] In the preceding First Mode, the marked sections are made by the marked sections 60a to 60b formed as indented portions on the edges of the portions 50a to 50b. In the preceding Second Modality, the marked sections are made by the marked sections 160a to 160b formed by placing stickers numbered "1" to "4" to the side portions 150a to 150d. In the preceding Third Mode, the marked sections are made up of the marked sections 260a and 260b formed by raised portions of the decorative panel 222. However, the present invention is not limited to these specific modalities. For example, the outlets or fins can be individually recognized when changing the color of each fin. Alternatively, as shown in figure 23, the marked sections 60a to 60d can be formed on the outer side of the outlets 32a to 32d on the main body panel 3a. Also, as illustrated in figure 24, the sections marked 60a to 60d can be formed directly on the fins 35a to 35d.

[00174] In the previous First Mode, the sections marked 60a to 60d are described as being relatively brighter than the matte finish of the environment. However, the present invention is not limited to these specific embodiments. For example, the marked sections can be treated to be shiny, or they can include a portion (shiny portion) to which a luminous fluorescent coating that glows in the dark is applied. In addition, the marked sections may have a color display using, for example, an LED (light-emitting portion) or other light-emitting materials that can be provided within the transparent resins that form the fins 35a to 35d.

[00175] In the preceding First Mode, the marked sections 60a to 60d corresponding to the exits 32a to 32d and the fins 35a to 35d are described as being formed by the counterclockwise arrangement of the figures representing the marked sections 60a to 60d. However, the present invention is not limited to this embodiment. For example, the marked sections 60a to 60d can be formed by the hourly arrangement of the figures representing the marked sections 60a to 60d. Also, the hourly / counterclockwise layout may not even be necessary.

[00176] Still, in the preceding First Mode, the present invention is described as being applied to the internal unit 1 which includes a main body of the panel 3a provided by the main outputs 32a to 32d and the auxiliary outputs 32e to 32h. However, the present invention is also applicable to an indoor unit that includes a main body of the panel provided only by the main outlets 32a to 32d.

[00177] Also, in the preceding First Mode, the indoor unit 1 is controlled using the wired remote control 83 connected to the main body of the indoor unit 1 by the communication cable. However, the present invention is not limited to this embodiment. The air conditioner can be controlled using radio transmission

[00178] Also, in the preceding First Mode, the total ventilation volume of the outlets 32a to 32d are adjusted by a single ventilation motor 41 provided for the outlets 32a to 32d, and with a single impeller 42 that rotates by being connected to the motor ventilation 41. However, the present invention is not limited to this embodiment. For example, the ventilation volume can be individually adjusted for outlets 32a to 32d with a ventilation motor and an impeller provided for each of outlets 32a to 32d. When the ventilation volume is adjusted for each of the outputs 32a to 32d., The status of each ventilation volume can be shown in a list in the display section 85. Also, when the operating mode (warm / cool) is switched on for each of the outputs 32a to 32d, the operating condition for each of the outputs 32a to 32d can be shown in a list in the display section 85.

[00179] Still, in the previous Mode, the display region 105 is adapted to show wind direction 1 for the direction of the however, the present invention is not limited - for example, the display section Completely Closed ", indicates that the fins are completely closed.

[00180] Also, in the preceding First Mode the wind direction main output 32c is previously determined for "wind direction 1", and only the wind direction positions of the selected fins 35a, 35b, and 35c are changed at the moment. However, the present invention is not limited to this embodiment. For example, the wind direction positions of the selected fins 35a, 35b, and 35c can be changed directly without previously determining the wind direction from main outlet 32c to "wind direction 1".

[00181] Also, in the preceding First Mode, the remote control 83 and the internal unit 1 are connected to each other via a communication cable W. However, the present invention is not limited to this mode. In the case of external power supply, the remote control can be connected to the outdoor unit via a wire, and the operating signals from the remote control can be sent first to the outdoor unit, and then to the indoor unit 1 with the power supplied from the unit outside.
